Swiss Tree Ring Chronology From 145 to -25 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from Rigi Klosterli, Switzerland. The data provides a chronology covering the period from 145 to -25 calendar years before present. This study was contributed by Schweingruber and is managed by the NOAA National Centers for Environmental Information.

Use Cases

• Calibrating climate models using tree-ring width as a proxy for past temperature or precipitation.
• Analyzing growth anomaly years within the chronology to identify extreme historical climate events.
• Cross-dating this Swiss chronology with other European tree-ring series to validate regional climate patterns.

Strengths

• Chronology spans 170 years, from 145 to -25 BP.
• Data is archived and curated by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1975, indicating potential methodological staleness.
• Specific sample depth, measurement parameters, and site details are not provided in the basic description.
